Specification of Letters Patent. Patltjed Feb. 28, 1922 Application iled October 22, 1917, Serial No. 197,861.' Renewed December 7, 1921. Serial No. 520,714.

To all w homv itmay concern Be it known that ILHERMAN J. BUCK, a citizen oi' the United States, resident of Ellwood City, lcounty of Lawrence, State ot Pennsylvania, have invented certain new and useful improvements in ConveyingApparatus, ci' which the following is a specification. y

My invention relates to an apparatus for conveying or transporting articles from place to place and particularly from a lower to a higher level, and the object ot the invention is to provide an arrangement ot carriers or conveyersand elevators by means of lwhich an article or package may be conveyed from the lower 'loor of a building toV ous constructions and combinations, all as hereinafter described and partially'pointed out in the claims..

ln the accompanying drawings forming part ot' this speciication,

l Figure 1 is a diagrammatic side view yof the carrier,

Figure 2 is a plan view of the same,

Figure 8 is a partial sectional view, showing-the delivery end ci' the elevator,

Figure 4 is a similar view, showing the receiving` end of the elevator', A

Figure 5 is a detail View, showing the lockingmeans.

In the drawing, 2 represent inclined elevators, suitably supported at 3 on adjacentfloors of a building. Thevupper end of each elevator is provided -with a shaft 4 having sprockets 5 engaging'chains 6. Bars 7 connect the opposite chains and engage the package or article tovbe transported, which rests upon a suitable licork 8. The chains are supported by suitable means, such as angie bars 9. At the lower ends of the eleadjacent.

an upperJi'ioor. ysupported'on vertical pivot 15S-at` the V,upper end-of'its elevatingsection and the vators the chains engage sprockets 10 on shafts Comparatively short delivering andreceiving carrier sections 12 and 13 are vprovided at the upper and lower ends of the elevators. Normally stationary carrier sections 14 and 15 are provided and suitably supported at 15 upon the floors of the buildrlhese carriersections l prefer to designate as the receiving and delivering sections, and l provide them on each floor in connection with the elevating section of that'looig so that, as will be hereinafter more particularly described in detail, a package maybe received on any iloor from oneA of the elevators leading from the Hoor below and a package may be delivered on anytlo'or to an elevator section leading to the floor above'.

The elevators and the gravity carrier sections'14 and 15 Vmay be of any ordinary or preferred construction, the sections 14 eX- tending along the floor to any point thereon Ywhere maybe desired to deliver a package, whilethe deliveringsection 15 may eX- tend to'any desired point on the floor from which it may be desired to send a package to a iioor above.- As shown in Figure 2, the

receiving section of a floor is preferably substantially in alignment with the elevatingl 'section leading from the floor beneath and the delivering section of that floor is preferably in substantial alignment with the ,ele-V vating section leading to the floor above, and in the preferred construction the two lines of conveyers are, substantially parallel and For the purpose of connecting one line with the other and providing a continuous line from a lower to an upper floor, as wheny it is desired to send a package from the basezment or receiving room tothe top of the building, ll-provide switch sections 16 `and 17. The former is arranged to form a continuation at the, top ot'an elevating section, while the latter is joined to the lower end ot' the adjacent Lelevating section leading to The switch section 16 is switch section 17 is pivoted at 19 at the-receiving endot" the adjacent elevatingsection, both sections being adapted to swing in a horizontal plane on their vertical pivots. Theopposite ends ot the switch sections from their pivots are provided with Suitable anti-friction rollers 2O bearing on vangle bars :2l supported by the adiacent stationary sections le and l5 and-the Svvitchv sections are thereby adapted to swing into or out of alignment with each other. The line position of the switch sections isindica-ted in Figure 2, `Where they are adjusted to connect the elevating' sections of one floor with the corresponding elevating section of the adjacent floor,` so that a package placedon the carrier at one iioor Will pass up to the floor nef-1t above and continued to an upper floor `without stopping, and if the switch sections on each floor are adjusted in alignment, the package Will continue to travel until it reaches the top floor or the end of the elevating apparatus. lf theattendant desires to divert a package at any floor, it is only necessary to swing a switch section of that floor into alignment ,With the receiving section thereon and the package, instead of passing on to the fioor above, will be diverted and pass onto `the stationary receiving station and conveyed to any desired point. l am thus able to start a package on a lower floor and pass it through Without stopping` to the top vfloor or upper level, or.V

l may divert the package at anyfioor` and l may also be able to deliver a package at any Vdoor to the elevating section of that floor for transportation and deliver to any upperfloor. K

lwillie gravitv sections may be of anypreferr-ed construction but preferably consist of side rails 23,` anti-friction rolls 24 and guide rails 25, suitablyjointed and rieidly braced. For the purpose of locking the switch sections lG and'lA in their different positions l provide suitable locking means such as depressions 21 on the bars 2l for the rollers Q0 to drop into, thus securing the kpivoted sections in alignnientfwitli each other in position to receive a package from a delivering section or deliver one to a receiving section. Stops 20 are provided at each end, of the bar 2l to prevent the sections being moved beyond their required distance.

It Will be understood that this apparatus can be extended or carried through any number of floors in a building, that it may be Vinade in different sizes andthe switch secvator section, and a gravity carrier sectionr pivotally supported in line with the delivery end thereof, of an inclined elevator section having its receivingend located out of line `With and at a lower level than the delivery `end of said first named elevatory section, a gravity carrier section pivotally Isupported in line with the receiving end of the second.

elevator section, and means suportiiig the free ends ofsaid pivoted carrierV sections, and permitting lateral movement thereof,

`whereby' said pivoted carrier sections ina vator section, and a gravity carrier section pivotally supported in line With-the delivery end thereof, of an inclined elevatorfsection having its receiving end locatedou't of line with and at a lovver level than the delivery end of said first named elevator section, a

gravity carrier section pivotally Supported Y in line with the receiving end ofthe second eievator section, a horizontal track supporting the free ends of said pivoted carrier sections, and permitting lateral movement` thereof, whereby said pivoted carrier sections may have their free ends arrangedfin line with each other, causing articles to pass from the discharge end of the firstnamed elevator to the receiving *end of the second named elevator, or the free ends of said,

carriers may be arranged out of linie` With each'` other, permitting .said elevators to be independently,operable, substantially as described. i. y 3. The combination with an'inclined elevator section, and a gravity carrier section pivotally supported in line with the delivery end thereof, of an inclined elevator section having` its receiving end located out of line withV and at a lower level .than'the delivery end vof said first named elevator section, a gravityA carrier sectionv pivotally Supported 'in line v with the receiving end vof the second elevatorsection, means supporting the free ends. of said pivoted carrier sections, and permitting lateral movement thereof, Whereby saidpivoted carrier sections may have their free ends arranged in line With each other, causing articles to pass fromthe discharge end of the first named elevator to the receiving end of the second named elevator,

or the free ends of said carrier may be arranged out of line With each other, permitting'said elevators to be independently operable, and means holding Vthe free ends of said carrier sections in either position, substantially as described.

, yIn Witness whereof, I have hereunto set ,'my. hand this l2 day of September 1917.
